Process of manufacturing linoxyn and like products especially intended for utilization in the linoleum manufacture.



rreoonss or To all whom it ma concernfg No Drawing.

subject of the German'Emperor, and res-i dent of Goslar, Germany, have invented a certain new and useful Improved Process of ManufacturingLinoxyn and Like Products Especially Intended fdr Utilizationin the ing is a specificationi.

in wetting a thin tissue with linseed-oil or varnish and allowing the such re ember-1 ing to oxidize and to stifii'en. The stifi'ening of this. first layer having taken place, liq-Q uid varnish is again spread upon it and this new coating of varnish is again allowedto;

stilten, this proceeding being repeated. many times until a solid coating of. sufficient thickness 1s adhering to the tissue. The

linonyn is well adapted for use in the manufacture of linoleum and likeproductsl The process described has however the incon venience of requiring a very long time (about 4 months) for carrying rtthrough, trials have been made to accelerate the course ofthe proceeding and endeavors in that line resulted in the so-called quick,

processes These quick-processes are cssen-' tially based upon anacceleration of the oxidizing process undergone by the'linseed-oil by means of blowing air into the mass of oil. Though a solidlinoxynbe also obtained in this manner, thequality of theproduct is sensibly inferior-tothat yielded by the Wal ton (sometimes called the scrim) process, a-s-the linoleum produced by the quick proc-- esses becomes easily cracked. Now the in-v ventor of the process forming the object of thepresent invention has found out that the inferior quality of thelin'ov'yn obtained by the quick processes is to be ascribed to the following facts: The \Valton linoxyn .is not. a chemically homogeneous mass, it. merely rcpresentsa colloidal solution of linoxyn in colloidal state of theVValton linoxyn that.

its specific properties are derived. v

The present. invention has for its object to convert the lmoxyn of Jlll'CllOF quality obr03 UTILIZATION me m a. mnnorac'ruxn. I

"The invention consists in intermingling such; inferior linoxyn, with linseed oil, this having forits effect the-production of a kind of swelledmass or colloidal solution. The mixing'of the l'inoxyn. with the linseed oil may be carried outinanysuitable man- -ner,' for instance 'in 'a kneading machine. The proportion of the materials to be mixed togetherfmay'be lqo p'arts of linoxyn obtained any quick process and from .5 to 20 parts of linseed oily: The mixing operation takesplace atthe ordinary temperature oftheatmosphere, @In some "cases, it may be advisable to raise: the temperature some what, say :to from to 80 centigrade inorder; to[acceleratejand"facilitate the mix ing operation. :It is advantageous to provide .woi 'kingconditiohs allowing a further absorption of oxygen by the product.

.Other oils thanlinseed oil, or varnish, may be, made use of and the process is also applicable in the manufacture ofoiled cloth and the like.

Having now fully described my said invention, what Iclaim and desire to secure by-Letters Patent cis:

1. In the manufacture oflinoxyn', the process which consists-in mixing a drying oil with linoxyn obtained by any quick process so as to obtain a colloidal solution, the proportions being from 5 'to 20 parts of a drying oil to 100 parts of linoxyn, whereby linoxyn having qualities similar to the linoxyn obtained by the scrim process is produced.

The process of iminufacti'iring linoxyn having qualities similarto the linoxyn obtained by-t-he scrim-process. consisting in mixing linseed oil with linoxyn obtained by any quick processso as to obtain a colloidal solution. the proportions being from 5 to 20 parts (if-linseed oil to 100 parts of linoxyn.

3. The process of manufacturing oil products, which consists in mixing a dry'ingoil with a previously stiffened and oxidized oil, so as to obtain a colloidal solution, the pro portion being approximately from 5 to 20 parts ot'a dryiugoil to a hundred parts of the solid oil product.
